Programming via the keypad on scanners is possible but it can be tedious.
Simple conventional channels are fairly straight forward but then attaching the label/alpha tag descriptors is even more tedious.
Trunk systems - even more. There is a step-by-step for basic programming posted
here.
The best way to program your radio is be PC software like Win500 and a programming cable. If you can cut and paste, that's all you need. If you want it to be a little easier, then you'll also need a Radio Reference Premium account to pull the data direct from the RRDB into the programming software.
To be clear, there are 3 different needs inditified above - all have a separrate source and cost:
- Win500 - download here (free 30 day trial - $30 for a license after that)
- Programming cable - $30
- Radio Reference Premium account - $15 for 180 days
If you get the software and the cable, I'll be happy to help you get it programmed.
